Abstract (en)
[origin: US2013156985A1] Provided is a water-proof sound-transmitting member that can be separated reliably from a releasing paper when an overhanging portion of a tab is pulled. The method for producing the water-proof sound-transmitting member (2) of the present invention includes the steps of producing a laminate (52a) by laminating a first layer (71), a preliminary membrane body (61), a second layer (72), and a preliminary tab body (63) in this order; inserting a blade (90) into the laminate (52a) from the first layer (71) toward the preliminary tab body (63) to cut the first layer (71), the preliminary membrane body (61) and the second layer (72) so as to form respectively the first adhesive layer (21), the water-proof sound-transmitting membrane (11) and the second adhesive layer (22), and providing, in a surface of the preliminary tab body (63) on a side of the second layer (72), a notch (13n) that is aligned with end faces of the first adhesive layer (21), the water-proof sound-transmitting membrane (11) and the second adhesive layer (22); and cutting the preliminary tab body (63) to form the tab (13).
